Diagnostics RAM: test of RAM Windows 7 64-bit

When the computer starts to fail, and cleaning the OS and optimizing it does not work, you need to start diagnosing the iron components. It is possible that errors occur through the fault of RAM. But you can not be sure of this without specialized programs that perform a test of RAM in Windows 7 64-bit. In Russian, the interface of preinstalled utilities is implemented, which is very convenient. Third-party software is equipped with only English localization, but is most effective.

The main reasons for the outage of RAM

The design of RAM includes several integrated circuits that are disconnected on the board and installed in the motherboard connector. This component is considered the most reliable among all major devices of the PC. The chance to buy a marriage is minimal, but it is possible. Besides him, other factors often come into play. Causes of memory failures:

• Static electricity ;
• Voltage drops in the network;
• Faulty or poor-quality PSU;
• Increased humidity in the room;
• Failure to perform regular maintenance (dust cleaning);
• Work at critical temperatures;
• Physical impact (hitting the PC case, falling laptop).

Symptoms of the memory

The failure of the RAM module leads to a variety of troubles. It is difficult to list them all, but the list of the main ones is quite realistic.

• BSOD is the surest and most frequent symptom of failures in RAM chips.
• Periodical shutdowns of the computer, failures when the operating system boots, hangs during the initialization of devices by the BIOS.
• Errors while running applications that require a lot of RAM. This includes graphic editors, 3D games, office packages, compilers.
• When artifacts appear on the display, you also need to test the RAM of Windows 7 64-bit. Although most often in this case, the video card is to blame.
• The computer refuses to turn on. Nothing appears on the monitor. At this time, error signals can be fed from the PC speaker. To understand what kind of failure is reported by the notification system, see the documentation on the site of the developer of the motherboard.
• Each attempt to reinstall Windows ends because of errors in its process.

Built-in utility

All OSs, starting with Vista, are equipped with a built-in tool that performs a Windows 7 64-bit test on the user's request. The computer does not need to install additional components. This is most convenient, but sometimes inefficient, for example, when the utility itself refuses to run due to RAM problems.

1. Complete all running programs.
2. Save important files and documents to an external storage device.
3. If possible, make a backup of the entire system.
4. Click on "Start", in the search area type mdsched and open the found application.
5. In the running program, the user will be offered a choice: a test of Windows 7 64-bit RAM without rebooting or checking after the next time the computer is turned on. Select the first mode is not recommended.

Background mode

Testing without shutting down the OS does not require a long wait. During the test, a window can be seen on the display, in which there is no information other than the filling indicator. It is designed to report the approximate percentage of the operation. If the RAM is OK, the utility will display an "No errors" message. In the event that the RAM slots are malfunctioning, the application will issue a list of fault codes.

As it was said earlier, the background check is not recommended, it does not give a complete picture. The fact is that in the RAM during the execution of the program functions, the data used by the operating system for its work is constantly stored.

The Windows 7 64-bit test run after the machine is restarted will start automatically. Its appearance resembles programs written for DOS. The whole process will take several tens of minutes. After finding the error at the bottom of the screen will appear red lines, with a description of the failure. In principle, if there is even one error, the verification procedure can be terminated, and the computer can be turned off, it just needs repair.

Independent Developer Tools

There are many applications on the Internet that test RAM. In their development involved both large companies and enthusiasts. The popularity of such programs allows you to mask worms and Trojans for them. Remember that when you download any executable file to your computer, you should check it with an antivirus. If the site offers to perform a test of RAM Windows 7 64-bit online, you know, this is a hoax. The browser can not get low-level access to physical devices and drivers.

Memtest86 + is a universal tool, whose algorithms are constantly improved. The application is distributed under the GPL license, which means that anyone can download it for free, but also participate in the development. The utility is optimized for testing any RAM up to DDR3. The program runs in DOS mode. This approach allows you to work with all memory cells. The verification tool requires an empty USB flash drive. Subsequently, it will become bootable.

Guide to create a bootable USB flash drive

1. Download memtest86 +. It's important to download the USB installer, not the ISO image. In order not to be mistaken, carefully study the information on the official website.
2. Unzip the archive into an empty directory and run the installer.
3. Select the drive to which the program files are copied.
4. Check the only possible checkbox. Be sure to save all the documents located on the USB flash drive, as it will be formatted.
5. Click Create.
6. When all operations are complete, click Next. Now on the USB flash drive there is a utility that will run a test of RAM Windows 7 64-bit. The laptop needs to be rebooted.
7. Go into BIOS settings and set as the first bootable USB device.
8. Exit with saving by pressing F10.

After turning on the PC, memtest86 + starts. It will automatically start checking. Total number of tests is nine. All of them are in a cycle. After the first circle at the bottom of the screen you can watch information messages that tell you if there were errors and if the RAM bars are working. Pressing the Escape key will turn off the utility and reboot the machine.

Memory fails, what should I do?

All further tips are for users who have minimal skills in repairing household appliances.

Disconnect the system unit and all peripheral devices from the network. Remove the computer cover and remove the RAM module. Examine the chips. If they are not chipped or any other defects, take an eraser and wipe the strap contacts. Sweep the garbage with a soft watercolor brush, and then treat the gilding with alcohol. Reinstall the bar and run the Windows 7 64-bit test again.

If the malfunction has not stopped, it makes sense to rearrange the module in the adjacent slot. If there are several modules, try to swap them.

A defective RAM module can not be repaired at home, and even in specialized workshops, it is unlikely that someone will take up this task. Therefore, when choosing a RAM strap, it is not worth chasing cheapness, you should choose a device from among the products of well-known manufacturers. Particular attention should be paid to the warranty period.
